Tesla Motors, Inc.’s (TSLA - Analyst Report) decision to build a $5 billion Gigafactory to meet its requirement of lithium-ion battery packs brought glaring focus on the shortage of supply of this emerging energy storage technology. Lithium-ion batteries are used by many auto manufacturers, including General Motors Co. (GM - Analyst Report), Navistar International Corp. (NAV - Analyst Report), BMW, Daimler AG (DDAIF - Snapshot Report) and Ford Motor Co. (F - Analyst Report). They are also used in cellphones, laptops, and other electronic devices as well as in the aerospace and defense sector.
However, the market for lithium-ion batteries has a lot of untapped potential. Tesla, for example, is facing problems in meeting the demand for its electric cars due to shortage of battery packs, which is limiting its production capacity. This was one of the chief reasons behind its decision to build a large-scale factory to produce lithium-ion batteries in collaboration with various partners. The electric carmaker’s Japanese battery pack supplier, Panasonic Corp. (PCRFY - Snapshot Report), is widely believed to be one of the partners.
By 2020, Tesla expects the annual lithium-ion battery production of the Gigafactory to exceed the global production in 2013. The factory will produce enough battery packs to allow Tesla to build around 500,000 electric cars annually by 2020.
However, Tesla’s Gigafactory will not start production until at least 2017. Till then, the focus will be on other lithium-ion battery manufacturers. Thus, it would be a good idea to invest in some companies that manufacture these batteries.
Let’s take a look at two stocks that are looking good at the moment:
Arotech Corp. (ARTX - Snapshot Report) has two business divisions – Training and Simulation and Battery and Power Systems. The Battery and Power Systems division manufactures and sells Lithium and Zinc-Air batteries and chargers for the Military.
Arotech reported a 150% positive earnings surprise in the third quarter of 2013.

According to Frost & Sullivan, the global market for lithium-ion batteries is expected to double to $22.5 billion in 2016 from $11.7 billion in 2012. Consumer goods and automobile sectors are driving the demand.
The share of the automobile sector in the lithium-ion battery market is expected to grow to 25% in 2016 from 14% in 2012, per the data from Frost & Sullivan. This represents a Compounded Annual Growth Rate (CAGR) of 37%. With the increasing use of lithium-ion batteries in consumer electronic products as well as efforts to promote the use of electric cars by many governments to curb pollution, the demand for these batteries is expected to rise.
